Gosh, sometimes I get a little miffed at the knee-jerk response to accidental breedings being Alizin!

Of course if you can catch an unwanted breeding very early on, then it would be best. But who is honestly going to recommend a bitch essentially give birth to well-developed pups and go through all that now?? There is a massive market for puppies, whatever their breed or crossbreed at the moment, so there will be no problems finding homes. And this poor owner has clearly already prepared all she can to raise a litter and bought a whelping box and got herself psychologically in place to do this... It's zero help whatsoever to go talking about Alizin now, give the poor person the help and support they really need!!
>s there anything else I should be doing now and is there any tips to help me through her labour, I am petrified of what could happen?
Regardless of the horror stories you've been told or even read, the vast majority of whelpings go smoothly and without any intervention needed. BUT, if you need expert help and yes, actually a midwife (virtually), I highly recommend you join Avidog.com - specifically their 'breeder' monthly membership package. It costs about $50 to join for a month and with that you get unlimited access to all their courses, which cover in detail how to raise a litter - including whelping - and which include access to a Facebook group with help 24/7 from the Avidog team of experienced breeders. Personally I wouldn't breed a litter without Avidog membership, I would consider it to be a risk I just don't want to take. If you're feeling lonely or confused by conflicting advice, join!! You can cancel the membership any time, so if you join now until pups go, you'll be paying $50/month for 2-3 months and get incredible help and advice.
>I have wish there was the dog equivalent of a midwife I could pay to be there but I don't think there is such a thing?
There is. They will be there in a Facebook group whilst you whelp and they will even Facetime or Skype you, if you need that.
>Can anyone talk me through what I need to know about her giving birth? What I will need to do and what I should leave her to do?
All that is covered in detail in the Avidog A-Z flagship course - there's a whole chapter on whelping.... otherwise it's a bit of a vague and general question.
>Also I have read to start feeding her puppy milk is this something you recommend
No, absolutely not- You should not be giving her any additional calcium before whelping because it can predispose her to eclampsia. (After the first pup is out, give all the calcium you like and then some - but not before.)
As for worming, given her history - which is unknown - you are totally doing the right thing. Roundworms can be very dangerous and if you are unsure of a bitch's worming history before breeding, she could have quite some worm burden to pass onto the puppies. An unknown worming history is just one time when worming as you have been is indicated. Besides which, there are many forum members here who routinely worm with Panacur during pregnancy and have no problems at all with it.
> I'm going to call a different vet tomorrow to see if they do call outs to be here at whelping
Please know that what your bitch needs to whelp safely and quickly, is to feel secure and PRIVATE during whelping. Asking a stranger to come into your house at this time, is only likely to leave her feeling worried and unsafe. Please don't ask strangers to come into your house unless there is a clear emergency and reason to do so (in which case you'd be going to the vet, not asking them to come out in most likelihood). You will only create problems if you stress the bitch, and cause whelping complications or hold-ups. Keep her calm and feeling safe with familiar people around her if possible. And even the most well-mannered bitch can be very protective of newborn puppies - if you want to avoid a scenario of her growling at the vet in your kitchen and not letting him come anywhere near....
